* A lubricant. Zinc Stearate is a zinc soap known for repelling water, and is used in the cosmetics and personal care industries as a lubricant. It is an insoluble salt made of commercial stearic acid, a mild fatty acid used as an emollient and lubricant, and is often combined with zinc oxide.
Certain salts, such as the dichromates, borates, and silicates, act as inhibitors to the aqueous corrosion of zinc. 2 S) is also harmless because insoluble zinc sulfide (ZnS) is formed. On the other hand, SO 2 and chlorides have a corrosive action because water-soluble and hygroscopic salts are formed.
